A print made by the photographer, or under the photographer's supervision, close to the time the negative was made, often within a few years.

A set number of prints of one photograph, for example 5 or 25, after which no more prints are made in that size. Each print is usually numbered and signed, such as 3/10.

A chemical bath used after the developer in film and print processing. It stops development quickly, usually with a weak acid such as acetic acid.

A strip of photographic paper exposed in steps of increasing time under the enlarger. After development it shows how the print looks at each exposure time.

An image printed with two inks, usually black and a second color or a second black or gray. In photobooks, duotones are used to print black and white photographs with more depth and tonal range than a single ink allows.

A printing process that transfers a photograph onto a copper plate, which is etched and then printed with ink. The result has very rich, deep tones.

An inkjet print made with pigment-based inks on acid-free, archival paper. Pigment inks resist fading much better than dye inks.

A name for high-quality inkjet prints, often used by artists and galleries. The word comes from French and means roughly "sprayed". It was introduced in the early 1990s for prints made on Iris printers.

A color print made on chromogenic paper, in which color dyes form during development. It is also called a chromogenic print. The name comes from Kodak's Type C paper of the 1950s.

A printing process that uses gum arabic, pigment and a light-sensitive bichromate salt. The paper can be coated, exposed and developed several times, often in different colors.

A print in which the image is made of pigment, often carbon black, held in hardened gelatin. Alphonse Poitevin developed the principle in 1855, and Joseph Swan patented a practical carbon tissue in 1864.

One of the earliest photographic printing processes, introduced by William Henry Fox Talbot in the late 1830s. Paper was soaked in salt water, coated with silver nitrate and exposed in contact with a negative in sunlight.

A print made with platinum instead of silver. It is also called a platinotype. William Willis patented the process in 1873, and commercial paper was available from 1879.

The standard black and white photographic print of the 20th century. The paper is coated with a gelatin emulsion containing light-sensitive silver halides.

Adobe Lightroom, software for organizing, editing and exporting photographs. The first version, Adobe Photoshop Lightroom, was released in 2007.

Changing and stylizing the colors of an image or film to create a certain mood or look. It goes further than color correction, which only aims to make colors accurate.

Increasing the contrast along edges in an image so that it looks crisper. Sharpening cannot fix a photograph that is out of focus, but it can make details look clearer.

Adding one color tint to the highlights and another to the shadows of an image, for example warm highlights and cool shadows.

Darkroom techniques for controlling the brightness of parts of a print. Dodging means holding back light from an area so it becomes lighter. Burning means giving an area extra light so it becomes darker.

Photography made outdoors after dark, using available light such as street lamps, the moon, stars or lit windows. It usually needs long exposures, a tripod, a fast lens or high ISO.
